The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat. All computers need a fan to prevent them over-heating for this very reason. Therefore heat is lost and energy is wasted.
Another example is a lightbulb. When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.
These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)
Matthias Jakob Schleiden is the German biologist that said all plants were made of cells
The correct answer is D. Porifera
Explanation
Porifera or sponges is a phylum that includes all simple primitive aquatic animals, distinguished by having a body full of channels and pores through which water flows. Sponges are formed by sets of cells that arrange in spicules which provide sponges a structure and spongin which is a protein. Additionally, sponges lack organs and are asymmetrical which means they have an irregular shape. Moreover, they stand out for having a great diversity of color and their sizes are varied from a few millimeters to more than 2 m high. So, the correct answer is D. Porifera.
Thermal, then kinetic, then electrical xx
